`k` के किस मान के लिए `(k-1)x-y=5,(k+1)x+(1-k)y=3k+1` के अनगिनत हल होंगे?

The value of k for which the graph of (k- 1)x+ y-2= 0 and (2-k)x-3y+ 1) =0 are parallel is k का मान जिसके लिए (k- 1)x+ y-2= 0 और (2-k)x-3y+ 1) =0 के ग्राफ समांतर हो, है-

Find the value of k for which the system of equation (k-1)x-y=5,(k+1)x+(1-k)y=(3k+1) has infinite no of solution

5x + 2y = 2k , 2 (k + 1 ) x + ky = (3k + 4)

{:(2x + (k - 2)y = k),(6x + (2k - 1) y = 2k + 5):}

{:(2x + 3y = 2),((k + 2)x + (2k + 1)y = 2(k - 1)):}

The number of values of k for which the lines (k+1)x+8y=4k and kx+(k+3)y=3k-1 are coincident is

The number of values of k for which the lines (k+1)x+8y=4k and kx+(k+3)y=3k-1 are coincident is __________
